SPWLA High Angle and HoriZontal Wells 
Special Interest Group

Mission Statement
Our mission is to create a collaborative forum where Geologists, Geophysicists, Petrophysicists as well as Geomechanical, Reservoir, and Completion Engineers can propose and deliberate solutions to mitigate the challenges in accomplishing the common goal of more accurate formation evaluation in high angle and horizontal wells.  The SIG encourages the integration of all data including core, drilling, logging, surface data, and any other available data to aid in attaining this goal.  The long term benefits of our SIG to the industry will be improved the formation evaluation,  drilling and well placement techniques, more complete reservoir understanding and more effective completion designs in high angle and horizontal wells.
